Title: Improvements in and relating to cigarette collecting mechanism for continuous rod cigarette making machines
IPC: A24C5/32
Filed: 1935-02-11
Abstract: 439,337. Cigarette-making machines. AMERICAN MACHINE & FOUNDRY CO., 511, 5th Avenue, New York, U.S.A. Feb. 11, 1935, No. 4408. Convention date, Aug. 3, 1934. [Class 130] In a cigarette-collecting mechanism in which a pusher displaces cigarettes laterally from an endwise travelling succession on to a travelling cigarette carrier having cigarette-retaining devices, the cigarettes are forwarded to the carrier by belts which grip the cigarettes substantially during the whole of their lateral displacement. Cigarettes delivered from the machine are gripped and spaced apart by forwarding-belts 34, 35, moving at a speed slightly greater than that of the cigarette rod, and are displaced laterally into axially-extending grooves 23a in a rotating drum 23 by a pusher 31. The belts have perforations 34b which register with and prevent injury to the ends of the cigarettes, and are arranged as closely as possible to the drum to grip the cigarettes during lateral displacement. The pusher 31 is given an orbital movement by means of crank-pins 26<a>, 28<b> carried on shafts 26, 28 driven from a shaft 11, which also drives the drum 23 through spiral gearing and the belts 34, 35 through sprocket wheels. To vary the space between the belts, a frame 35b, Fig. 4, supporting the belt 35 is hinged at one end on a pin 42 and carries an adjustable screw 43 resting on a fixed lug at the other end, and an adjustable stud 44 having one flat surface is provided near the pin 42. Any short cigarettes in the space between successive cigarettes are ejected by a prong 31a adjustably secured to the pusher 31. The grooves 23a are provided with ports 23<b> communicating with a suction chamber 37 which extends from a point adjacent the belts 34, 35 to a point at which the cigarettes are removed by delivery belts 39 running in grooves in the drum. The chamber 37 is formed in a stationary block 38 which can be adjusted to vary the points at which suction is applied by moving a set-screw 38a, Fig. 4, in a slot 38b. To secure accurate alignment of the cigarettes on the drum, a plate 40, slidably mounted on the frame 35b and reciprocated by a crank-pin 41 and connecting - rod 41a, engages the ends of the cigarettes and pushes them into contact with a flange 23<c> on the drum. Bosses 23<d> on the plate 40 and the flange 23<c> compress the tobacco in the ends of the cigarettes. If the prong 31a is omitted, a reciprocating tube 51 provided with prongs 51<a> prevents lateral displacement of the cigarettes delivered to the belts 34, 35. In a modified construction, the drum has a smooth cylindrical periphery provided with longitudinally - extending suction openings. Specification 412,502 is referred to.

In an asynchronous MHD generator where the fluid moves faster than the energizing travelling magnetic field, the lateral shortcircuiting conductors forming the side walls of the duct comprise a plurality of individual electrically insulated component conductors, each conductor having its longitudinal direction parallel to the axis of the duct. To further reduce eddy current losses the component conductors are shaped such that they lie along at least part of the lines of magnetic flux. Various forms of conductor are shown including ones where the lengths of the individual component conductors, which may be of different thicknesses are substantially equal. It is also stated that the conductor may be bisected on the mid-plane of the duct and rejoined with the interposition of insulating material. The conductors may be produced by winding an insulated copper foil into rectangular shape and then dividing it to give the desired equal length component conductors thereby producing both lateral conductors in one operation. If foil of varying thickness is used, winding commences at the thickest part.

Abstract: 5 9 7 , 8 1 9 . Proofing textiles against fungi. MONSANTO CHEMICAL CO. Feb. 27, 1945, No. 4903. Convention date, May 1, 1943. [Class 140] A textile is impregnated with a fungusproofing agent which is insoluble in aqueous solutions in the pH range of 2.8 to 13, said agent being a copper salt derivative of 8- hydroxy quinoline. The salt may be formed within the interstices of the textile by the reaction of an acid salt of 8-hydroxyquinoline with a water-soluble copper salt (two-stage process), or the textile may be treated with an aqueous solution of the copper salt derivative of 8-hydroxy quinoline having a pH of 2.7 or lower and then the pH raised above 2.8 by adding alkali or alkaline materials (single-stage process). In the two-stage process, the textile may be soaked in an aqueous solution of a copper salt such as the acetate or sulphate, removed after impregnation, rendered free of excess salt solution if desired and transferred to a solution containing 8-hydroxy quinoline desirably present as the acetate, sulphate, or phosphate. The textile is then removed from the solution, excess solution expelled by e.g. pressure rollers, and the treated textile dried or washed and dried. In the single-stage process, the textile is treated with an aqueous solution of the copper salt derivative of 8- hydroxyquinoline made soluble by reducing the pH to 2.7 or lower by the addition of acid (e.g. 0.1 NHCI). The impregnation may consist of a single washing operation at room or elevated temperature or a boiling operation. After impregnation, the pH of the solution is raised above 2.8 by adding ammonium hydroxide, sodium hydroxide or sodium carbonate. The textile is then removed from the bath, excess liquid expelled and the textile dried. In the two-stage process in place of an acid salt solution, the free base, 8-hydroxyquinoline may be employed in an organic solvent. Textiles specified are yarn, twine, cord, rope, fringes, fabrics, osnaberg fabric, cotton duck fabric, khaki fabric and cotton-wool fabric. The term "copper salt derivatives of 8-hydroxyquinoline " covers the compounds formed when a copper salt reacts 8-hydroxyquinoline or an acid salt thereof.
